To all when?, itmay concern: f f* n Be it known that L'ROY M.,M owRY,-a citizenof theUnited States, residing at Nezpe'rce, in the countyof'Nezperce andl State of Idaho, .have inventedva newr 4a-nd 'useful lGar-Door ieaiion of Which the lfolloW-ingis :xi-speci*-V 'It'is the object ofthe present irvdntion to provide ,an improved door` 'for L graincars and the like and the-primary aun of the 1nvention' is to 'so 'construct the door that it' may .b e moved to position beneath .the` rootj of the-carand be entirely out of the Way ".vhile '.the ca'r is beingunloaded.

4The door embodying the present invenf' ti on consistsof a pli; ralityof sectionsV which may-.be independentlynoved to the position stated or.,l all of .the ,sect-ions maybe simultarneouslyjmoved.

1 A .urther aimof the Invention 1s to `so construct the`sectionsthatftheyA will have a tight fitin Vthe doorway ofthe car and IWill j In the. dawings-1-Figure1 isa from ele;

ration of the door" embodying the present invention, the same being ,arranged'in the loorwayof-astructure, such for example as a grain c'ar.` 'Fig.`2 is'` av vert-ical sectional;

view on -the line 2-2 of `Fig. 1 "looking the' 'directionjindicated lbyV the arrow. Eig.

3 is a horizontal sectional lview. AFigfl is a` view similar to Fig.,`1 illustrating the-.sec-

. tions of the'doorpart1y;elevated. In -th'e drawingsgthe oar'is .indicated in' general-by' thefreference character.- @,ithe

' character Rand thefioor thereof," by v.they

roof thereofis designated -by the reference character F. The sidewall ofthe car is provided With the'jus'ualE doorway .and aty .each side' of the doorway in the 4ide of the car, there is arranged. a. guidel ormed with aV-sha'ped groove 6. Atrack '7 is secured to each guide 5 at one side of the grooveand terminating' at .a height substantially in alinement with thetopof the door Way, while, a track '8 issecured t'o. each guide at the otherfside ofthe groove therein, and eX 'tends rearwardly at its Aupper end as will presently appear. Each track 8, beyond itsl portion whichy extends along the guide 5, is

Y bent inwardly and upwardlyas at 9 and-in-A .wa'rdly' beyond, thisbentfportion is stepped as yat 10, the 'track termlnating inanup-J 4Walrdly inwardly inclined portion 1 1` and the stepped portion ofthe track exte-nc'lin'gbe- Heatht-he'roof R of'the car.

The door embodying the present inventionconstruction and as ecjtion 18' substantially 'V consists ot 'a number sections 12' loflike .like the other sections." Eaclrsection 12,'*as

"vell yas'the section '13, .has itsflipper'ledge beveled from the' oppositefaoesl'ofithe sec' -I rtions 'whereby to.l 'assume an inverted V- form and 1s lpreferably covered withfa strip y14 lof sheet metal." 'Eachfsfection y12 hasii'ts 4-under edge formed With a V-shaped groove v and faced with sheet metal as at 15,.'the groove in the lowerl edge of each section 212 being' 4.arranged to receiveXrthe upperedge ofsthe section `.next below, in the hianer illustrated in Fig. .2 of the drawings, when ,the sections are in position to close thedoor-y way in theside of theca-r. ,Section'13 has.

a rectang llar lovveredge and -rests at itsv said edge uponthe 'floor F 'of the car. `VVhei'i the sections comprising the door are in positionv 'to close the-doorway, they are received, inv

superpo'sedgreliaton, between' the Vtracks 7 and 8 and in order that grain. willbe'pre.-

vented from sifting `from lthe car around the"v lends of the. doors, their vsaid' ends arebeveledl to- V-form as slt-16 land faced .as in they Lease of' their upper and loweredges, and-fit fsnu'gly lin the 'grooves v6 4in the guides. 5. It willflbe understood ofcourse that'the sec- 'tions are`sl i dable in these groovesand that they 1na.y' tra-'vel jover thetrack 8' so as to assume either-the' position .shownv in' full- ,lines or in `dotted line'sin Fig. 2 ofV the drawings. In lorder thatthesections may be readily elevated, there'ispro'vided upon each ofthesection's, apair ofhooks 17 which enfgage *inl eyes 18vat intervals'in the lengt-h of cables 19.. These cables-are; trained through 'guides at theroof of the'car' and wind upon a v-dr'unjQO valso mounted beneathA the roof [of the. car and rotated .through-the mediuni of a crank handle 21.

'rot-atedso aswind u the cables 19 andas this is done, the 'sectlons will be simultane` ously elevated or slidfupwardly upon the traek'.'4 It will be observed-that the-hooks g .17 are nearly straight.4 and consequently, as thefsec'tions movev overv the curved portions 9of-'fthe tracks,`.the hooks willjle'ave theA eyes and; the sections will be` then-advanced 'by the sections nxt-belovv,"upon,which lat ter sections, -orsection, a 'pull is' still .eX-

los;

erted by' 'the 'cables'. ll As- .the sectionsad-` Vance over the stepped portions of the track, the foremost section will eventually ride ,up the inclined portion 11 of the two tracks and will finally dro intoV the position shown in dotted lines m Fig. 2 and in full lines in Fie'. 't of the drawings. This section then serves as an inclined plane upon .which the next section in order, may move,

tions of a door located at either side of the What is claimed is l. The combination with a structure hav.- ing a doorway, of spaced tracks arranged Within the structure, each ot' said tracksl having a series of stepped port-ions extending beneath the roof of the structure, the steppedl portions of each track alining, a plurality of door sections one -to each stepped portion of each track movable upon the tracks'and arranged to seat upon the reu spective alined pairs of stepped portions thereof in` overlapped relation, and means for elevating the sections, said means comprising a cable having a pluralitlvT of eyes located at'intervals in its length, and hooks upon the sections .p engageable in the eyes.

2. The combination with a. structure having a doorway, of spaced tracks arranged within the structure` each ofsaid tracks having a series of stepped portions extend .ing'beneath the roof of the structure, the

stepped portions of each track alining, a

.plurality of door sections, one to each stepped portion of one track movable upon the tracks and arranged to seatupon the respective alined pairs of stepped portions thereof in overlapped relation, and means vfor elevating the sections, said means comprising a cable having a plu 'ality of Veyes located at intervals in its length7 and hooks upon the sect-ions engageable in the eyes, the said hooks being arranged to disengage from the eyes prior to movement of the sections over the stepped portions of the tracks.

3. The combination with a structure having a doorway, of guides located one at each side of the doorway and having Vshaped grooves, a pairngt tracks disposed upon opposite sides of said guide, one of said tracks being longer than the other,` and bent away therefrom and provided with' a series of stepped portions, and a doorconsisting of a plurality of sepa ate sections having V- shaped ends fitting slidably in the guides adapted to have its respective sections elevated to seat within the stepped portions of the track. v

4. The combination with a structure hav ing a doorway, of guides located one at each sideof the doorway and having V-shaped grooves. a pair of tracks disposed upon opposite sides of said guide, one'ot said tracks being` longer than the other and bent away therefrom and provided with a series of stepped portions, and a door consisting of a pluralit)T of separate sections having V shaped ends fitting slidably in the guidesy and having intertitting upper. and lower edges and adapted to have its respective sections elevated to seat within the stepped `portions of the track.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
